To access service mode in Monster Truck hold Horn and Nitro on startup
There are multiple revisions of the CPU hardware, the SSD 2000 / SSD 2002 chips definitely add more opcodes

/* The 'XaviXPORT' isn't a real console, more of a TV adapter, all the actual hardware (CPU including video hw, sound hw) is in the cartridges and controllers
and can vary between games, see notes at top of driver.
According to sources XaviX Tennis should be a standard XaviX CPU, but at the very least makes significantly more use of custom opcodes than the above titles
which only appears to use the call far / return far for extended memory space.
Furthermore it also seems to require some regular 6502 opcodes to be replaced with custom ones, yet the other games expect these to act normally. This
leads me to believe that XaviX Tennis is almost certainly a Super XaviX title.
The CPU die on XaviX Tennis is internally marked as NEC 85054-611 and is very different to the two below
Radica Monster truck die is marked SSD PL7351 with SSD98 also printed on the die
Radia Ping Pong die is marked SSD PA7270 with SSD97 also printed on the die (otherwise looks identical to Monster Truck)
Boxing, Baseball 2 and Card Night all have the SSD98 logo
Boxing, Bass Fishin' and Card Night are all PA7351-107. Baseball 2 looks like PL7351-181.
Star Wars Saga Edition also seems to be making use of additional opcodes, meaning it could also be Super Xavix, or something in-between (unless they're
caused by the bad dump, but it looks intentional)
